5-6 conversion

Recommended Posts

Well I've purchased a 2001 wrx bug and I'm wanting to change the gearbox from a 5 speed box to a 6 speed box.

I've heard of it being done but have no clue on how to find the right one or what else I might need to change.

Any help is very grateful, cheers guys [emoji106]

Usually you need to change your prop, rear diff and drive shafts if I remember rightly. Quite often you can buy everything you need as a set from a car that's being broken. It's an expensive process though.

6 speed conversion kit will cost about £1.5k + fitting + new clutch, might as well fit a new uprated clutch while the box is off [emoji6]

If you didn't swallow your own tongue at the price here's what I suggest.

Look on your current 5 speed box bell housing (near the starter motor) for a white sticker with a code starting with ty***

Google the impreza ty*** code to find the gearbox and rear diff ratio

If you can find a 6 speed with the same ratio as the current 5 speed the minimum you'd need to buy (cheapest option) would be ....

6 speed box (same ratio)

6 speed cradle

6 speed prop

6 speed gear linkage,stick and knob

As the 5 speed


Clutch slave


Starter motor

Speedo sensor

Front Drive shafts

Rear diff (if the same ratio)

Are all compatable although I chose to run the 6 speed flywheel, clutch, slave and starter motor ,mainly as they were 10 yrs newer and came in the kit [emoji6]

Mattyb (reputable breaker) will probably have what you need in stock let me know if you're definitely still interested and I'll point him in your direction bud

Just been to Richard Henrys (Scooby specialist) in Bradford and he's told me I can put a uk sti 6speed box straight on as it is a direct match. However I will need the prop shaft for it and the clutch will also fit, luckily my click is almost new ;)

Google the ty number anyways bud cos if it's had a gearbox change before sombody might have put a shorter ratio box and diff in. (If it's a standard UK box it will be a 3.5.4 ratio)

You will need the other bits I mentioned as well (cradle ,prop,gearstick ect)

Yeah that's mattyb ' s firm won't go wrong with his bits bud [emoji5]
